hmmmmmm

maybe start at like a 150 main and go down from there, not sure about the pilot

I seen many running the 150 in them carbs when I was looking. I looked in what's your jetting sticky.

1,000 ft to 3,000 ft is quite an elevation change. If you're going back and forth between the two, you'll probably need to jet it rich enough to survive at 1,000 and take your airbox lid off at 3,000

150 is going to be fat with the airbox lid still on even with holes in it. It would be a good starting point for jetting passes and plug chops, probably. I would probably stick a 45 in the pilot hole just to see how it ran. If it's too rich it'll sputter as you take off and the air screw will have to be way out past 2.5 turns to keep it idling.
